Going from 87% of 2 cores, to ~10% of an entry level CPU is good, specially when the load is taken care of by existing chips. I agree on that point. I would rather have ~10% or ~20% then the regular 57% per core on my Core 2 Quad system when I view H264 channels of my provider. Yes, I agree. Just pointing out that you certainly do not need a quad core, that's all. Also, the price of the cpu is the same whether you're using 87% or 10% of it. ;) The point is you can already have cheap HDTV without using the new Nvidia api. Well, in my case I do. When I view BBCHD, ArteHD, AnixeHD or the AstraHD channels I don't encounter many problems. Image is clear and no stutter. But as soon as I watch the 1080i/H264 channels of my provider (Canal Digitaal) on Astra 23.5e, I have major stuttering. BravaTV in HD doesn't have much problems, but NGC HD and Discovery HD is an other matter. My Core 2 Duo just couldn't handle it with FFMPeg and Xine-lib 1.2. But since I've put in a Core 2 Quad, I'm able to watch those channels even with fast moving images :) I'd like to have full-HDTV on a single x86 mini-ITX board. I'm now seeing this will happen soon enough, and I'll wait until then before I spend money on new hardware. Yes it's nice! My goal is diskless, fanless, low power consumption dedicated HDTV box. Very small, very low cost! I again agree :) I would like an additional HDTV box in my bedroom. It needs to have the options you wrote. But I don't want a Popcorn or some other kind of device. I want the option to enhance it myself (flexability) so I'm waiting desperately for GPU based decoding of H264 and VC-1 transport streams :) Niels Wagenaar ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Re: [vdr] New Video Decode and Presentation API from NVidia
I'm new to using git to obtain sources, and can't seem to get the vdpau sources into my local ffmpeg git tree. In /usr/local/src/VDPAU i've pulled the ffmpeg sources creating a ffmpeg-git directory with the usual ffmpeg data in it. I then try to pull the vdpau sources with git clone --reference /usr/local/src/VDPAU/ffmpeg-git git://repo.or.cz/FFMpeg-mirror/ffmpeg-vdpau.git. This creates a ffmpeg-vdpau directory with nothing but .git in it; no sources. Anyone with more experince in this have any pointers on what I am doing wrong? I'm in the US running vdr 1.6.0-2 on an AMD x2 4600+ using ffmpeg and xine and have no problems with HD MPEG2 and H264 up to 1080i (some occasional stuttering), but the 1080p channels fail miserably. While waiting patiently for xine to support VDPAU, I'd like to get the driver and ffmpeg working with Mplayer to try things out.

You must live under a rock if HD content isn't already common where you live/from your provider! Here is NA there's tons of HD channels, with many more coming soon. Also, building a HD-capable pc is already cheap. You don't need some expensive cpu with GB's of ram and so on. My test box (which uses the on-board gpu) does HD and was only cpu-$40 + ram-$25 + mainboard-$65. cpu is amd x2 4400, corsair 2x1GB stick ram kit, mainboard is msi k9n6sgm-v. $130 USD and I had a new dvb test box that does HDTV. ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Re: [vdr] New Video Decode and Presentation API from NVidia
Good news! Competition with Intel benefits us all :) On Fri, Nov 14, 2008 at 9:03 PM, Goga777 [EMAIL PROTECTED] wrote: FROM XORG lIST I'm pleased to announce a new video API for Unix and Unix-like platforms, and a technology preview implementation of this API from NVIDIA. The API is called VDPAU (Video Decode and Presentation API for Unix). The current API documentation is here: ftp://download.nvidia.com/XFree86/vdpau/doxygen/html/index.html Some highlights of VDPAU: * Defines an API for GPU-accelerated decode of MPEG-1, MPEG-2, H.264, and VC-1 bitstreams. * Defines an API for post-processing of decoded video, including temporal and spatial deinterlacing, inverse telecine, and noise reduction. * Defines an API for timestamp-based presentation of final video frames. * Defines an API for compositing sub-picture, on-screen display, and other UI elements. Note that VDPAU does not address content protection. Some highlights/limitations of NVIDIA's current implementation: * Supported on NVIDIA GPUs with the NVIDIA second generation video processors (see the end of this announcement for a complete GPU list). * Currently, only one video stream can be decoded at a time; we hope to lift this restriction eventually. * Available in the 180.06 NVIDIA public beta release: http://www.nvidia.com/object/linux_display_ia32_180.06.html http://www.nvidia.com/object/linux_display_amd64_180.06.html http://www.nvidia.com/object/freebsd_180.06.html http://www.nvidia.com/object/solaris_display_180.06.html The VDPAU support in the NVIDIA 180.06 beta release is still very preliminary. We are aware of cases of visual corruption and in some cases GPU hangs. We will be working on these issues over the next several NVIDIA driver releases. While NVIDIA's VDPAU implementation is not ready for end user use yet, it should be far enough along that interested application developers can begin working with it. Additionally, NVIDIA has developed patches to ffmpeg and MPlayer to demonstrate a video player using VDPAU: ftp://download.nvidia.com/XFree86/vdpau/mplayer-vdpau-3076399.tar.bz2 These patches include changes against libavcodec, libavutil, ffmpeg, and MPlayer itself; they may serve as an example of how to use VDPAU. Once we do some further testing, bugfixing, and cleanup, we will contribute the MPlayer patches to the MPlayer developers. If other hardware vendors are interested, they are welcome to also provide implementations of VDPAU. The VDPAU API was designed to allow a vendor backend to be selected at run time. Thanks, Andy Ritger Manager, NVIDIA Linux Graphics Driver VDPAU is currently supported on the following NVIDIA GPUs: Desktop GPUs: GeForce 200 Series GeForce 9 Series GeForce 86xx Series GeForce 85xx Series GeForce 84xx Series GeForce 8800 GTS 512 GeForce 8800 GT GeForce 8800 GS Mobile GPUs: GeForce 98xxM GeForce 9700M GeForce 96xxM GeForce 9500M GeForce 9300M GeForce 9200M GeForce 8800M GeForce 8800M GTS GeForce 8800M GTX GeForce 8600M Motherboard GPUs: GeForce 9400 GeForce 9300 GeForce 9100 GeForce 8300 GeForce 8200 VC-1 support in NVIDIA's VDPAU implementation currently requires GeForce 9300 GS, GeForce 9200M GS, GeForce 9300M GS, or GeForce 9300M GS. ___ xorg mailing list [EMAIL PROTECTED] http://lists.freedesktop.org/mailman/listinfo/xorg ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
